Problems with T-Molding Installation

[SuperRabbit0]

I am building a small tabletop arcade which I am installing 1/2" T-Molding on.

The problem that I am having is that my cabinet features several inside corners that have a very small (< 2") leading edge on one side.  

I am having a very difficult time getting the T-Molding installed on these inside corners as the T-Molding keeps leaving a small "gap" that I don't really like right in the corner.

As the T-Molding is white, I was considering filling the gap with white filler but thought I would check here to see if their is some techniques I could try that would make this install better.

I did cut away the backside of the T-Molding at these corners,  but maybe too much or too little....

cut the track off the tmolding at the corner in question.  Then glue it around the radius.  That's how you get it to bend.

The rest of the track will stay in the slot and hold it tight.
